“C:\DBs\BlogAppDB.mdf”指定的路径不在有效目录中

Question

我想使用我的 localdb 上已经存在的 mssql db 示例运行我的 Web 应用程序。我已经做了配置。但是我有一个像下面这样的错误，我的 .mdf 和 .ldf 文件在那里。

您的数据在您的本地机器（主机）上。它在 Docker（Docker 机器）中不可用。您可以使用卷将本地机器目录映射到 Docker 机器目录。例如：

volumes:
  - C:\\DBs\\BlogAppDB.mdf","C:\\DBs\\BlogAppDB_log.ldf:/var/opt/mssql/data

在您的问题中，您已经注释掉了这些卷。但是该卷被命名为BlogDB。如果你想在 Docker 机器中持久化数据，那很好。但要从本地机器映射目录，您需要提供路径（例如，./my-directory/）。

如果 Windows 风格的路径似乎不起作用，请查看此QA。
